As in her Gone from Home (reviewed above), Johnson here explores the themes of what makes a place home and which people family. Fourteen-year-old Marley's tranquil life in Heaven, Ohio, turns hellish the day her family receives a letter from Alabama. The note (from the pastor of a church that was destroyed by arson) requests a replacement for Marley's baptismal record, and reveals that ""Momma"" and ""Pops"" are really Marley's aunt and uncle, and mysterious Jack (an alleged ""uncle"" with whom Marley has corresponded but doesn't remember) is her true father. In this montage of Marley's changing perceptions, Johnson presents fragments of the whole picture a little at a time: images of people, places (the Western Union building ""1637"" steps away from Marley's house) and artifacts (a box filled with love letters between her birth parents) gain significance as Marley begins to make sense of the past and integrate her perceptions into her new identity. The author's poetic metaphors describe a child grasping desperately for a hold on her reality (""It was one of those nights that started to go down before the sun did,"" she says of the evening the fateful letter arrives). The melding of flashbacks and present-day story line may be confusing initially, but readers who follow Marley's winding path toward revelation will be well rewarded. Ages 12-up. (Sept.)
